4.7 Temperature monitoring
When the temperature is outside the measuring range, this is indicated by “<<“(15
below °C) or “>>” (above 45 °C). This limit is fixed.
• Calibration must be carried out before every application.
• Zero point calibration is automatically carried out when the pressure sensor cable
is plugged in. However, it can also be initiated manually via the
IBP
setting screen.
• In order to avoid wrong results based on physiological zero-point drift of the used
sensor, recalibrate the sensor every 24 hours.
Note
If the pressure sensor's position is moved after or during calibration, this might lead
to wrong low or high values.
1. In accordance with the manufacturer's instructions, open the relevant valve(s) to
equalise the system pressures as is shown in this example.
2. Press the IBP alarm button.

To ensure that children and neonates have sufficient air to breathe, it is vital that
the "System > Patient" ("Adult", "Pediatric", "Neonatal") and the CO
2
settings be
checked. The flow rate for CO
2
measurement must be 120 ml/min for children and
90 ml/min for neonates.
• Depending on the sensor type, the sensor can be applied to the ear, the skin or per
rectum.
• The minimum measurement duration to achieve a measured value, independent
of the measuring site, amounts to at least 2 minutes.
